Configuring Domain Name Files
Create or Modify the Resolver File
Create or Modify the Resolver File
The resolver file (
RESLVCNF.NET.SYS
) is an initialization file for the
domain name resolver. It contains information needed by the network
to determine how to resolve a domain name to an IP address. This file is
read by the resolver routines the first time they are invoked by a
process.
to determine how to resolve a domain name to an IP address. This file is
read by the resolver routines the first time they are invoked by a
process.
To create the resolver file, perform the following steps:
Step 1. Copy the sample file,
RSLVSAMP.NET.SYS
, to
RESLVCNF.NET.SYS
.
Step 2. Modify
RESLVCNF.NET.SYS
using any ASCII editor so that it contains
information about the name servers, domain, and search order for your
network. The keywords included in the file are described under “Fields.”

To modify an already existing
RESLVCNF.NET.SYS
file, simply use your
editor to update and save the existing file.
Fields
Each entry in the resolver file consists of a keyword followed by a value
separated by white space. The keyword and its associated value must
appear on a single line and the keyword must start the line. Figure 12-1
shows an example of a resolver file. Comment lines start with a pound
sign (

domain
Enter the local domain name. Most queries for names
within this domain can use short names relative to the
local domain name. If the host name does not contain a
domain part, the root domain is assumed. If more than

The domain name is composed of labels, with each label
separated by a period. Each label must start with a
letter or digit, and have as interior characters only
letters, digits, hyphens (-), or underbars (_). A domain
name may have any number of labels, but its total
length, including periods, is limited to 255 characters.

Domain names are not case sensitive.
search
The

entry is optional and indicates the order in
which domains should be searched for host name
lookup. You should add a
